Description: Value of the primorial function for nonnegative integers. (Contributed by AV, 28-Aug-2020.)

Assertion

Ref	Expression
prmoval	⊢ (𝑁 ∈ ℕ0 → (#p‘𝑁) = ∏𝑘 ∈ (1...𝑁)if(𝑘 ∈ ℙ, 𝑘, 1))

Distinct variable group:   𝑘,𝑁

Proof of Theorem prmoval

Dummy variable 𝑛 is distinct from all other variables.
